This Major Research Instrumentation award supports the acquisition of a transmission electron microscope (TEM) at North Carolina State University (NCSU) equipped to study a broad range of interdisciplinary materials. The microscope enables interdisciplinary research into energy storage and conversion, biological compatibility, environmental mediation, and materials exhibiting exotic properties such as superconductivity. While a TEM is usually operated at room temperature and under high vacuum, this microscope enables imaging with the sample at temperatures ranging from cryogenic to a thousand degrees Celsius, in a variety of liquids, or exposed to various gases. These conditions can closely match those where the materials operate and thus provide new scientific insights. The TEM is integrated into several activities at NCSU including the opportunity for K-12 students to experience scientific instrumentation first hand. Results from the microscope are also incorporated into a centerpiece educational outreach program that exposes the general public to atomic resolution electron microscopy through the unintimidating medium of art.This Major Research Instrumentation award supports the acquisition of a transmission electron microscope (TEM) at North Carolina State University (NCSU) equipped to investigate hard and soft matter at conditions where dynamic phenomena occur. The instrument catalyzes new research in the Research Triangle by enabling fast in situ imaging in a variety conditions including low temperatures (down to cryogenic), heating, biasing, mechanical loading, gas, and liquid. Further, a high-speed camera is equipped to capture detailed structural changes during these experiments. These capabilities, in combination with the capability to capture spectroscopic and three-dimensional data, will accelerate intellectual output by empowering researchers to make new, atomic scale insights, with greatly improved temporal resolution, and at conditions relevant to material properties. With a broad spectrum of materials that can be studied with the instrument, and integration into the NSF funded Research Triangle Nanotechnology Network, the acquisition will impact research across departments at NCSU, in North Carolina, and beyond.

这项重大的研究仪器奖支持北卡罗来纳州立大学（NCSU）的传输电子显微镜（TEM），该奖项能够研究广泛的跨学科材料。显微镜可以对能源存储和转化，生物兼容性，环境中介和具有外来特性（例如超导性）的材料进行跨学科研究。虽然通常在室温和高真空下进行TEM进行操作，但该显微镜可以在温度下的样品进行成像，从低温到千摄氏度，在各种液体中或暴露于各种气体中。 这些条件可以与材料运行的那些条件紧密匹配，从而提供新的科学见解。 TEM被整合到NCSU的几项活动中，包括K-12学生亲身体验科学仪器的机会。 显微镜的结果还纳入了一个核心教育外展计划中，该计划通过不限制的艺术媒介使公众暴露于原子分辨率电子显微镜。这项主要的研究仪器奖支持在北卡罗来纳州州立大学的传输电子显微镜（TEM）的收购大学（NCSU），能够在发生动态现象的条件下研究硬和软物质。该仪器通过在各种条件下进行快速的原位成像，包括低温（降至低温），加热，偏见，机械负载，气体和液体来促进研究三角研究的新研究。此外，在这些实验过程中，高速相机可以捕获详细的结构变化。 这些功能结合了捕获光谱和三维数据的能力，将通过赋予研究人员能够提供新的，原子量表的见解，并具有大大改善的时间分辨率，并且在与材料属性相关的条件下，可以加速智力输出。借助可以使用该仪器研究的各种材料，并将其集成到NSF资助的研究三角纳米技术网络中，该收购将影响整个NCSU，NCSU，北卡罗来纳州及其他地区的研究。
